IIVI-PROi/EMEN'T IN APPARATUS FOR SPRINKLlNG STREETS, Sac.

Specification forming part of Letters Patent No. 7,273,`dated April 9, 1850.

To a/ZZ whom t may concern,.-

Be it known that I, JOSEPH D. PRICE, of Smithsburg, in the county of Vashington and State of Maryland, have invented certain new and useful Improvements in Machines for y Sprinkling Streets with Vater, and for other purposes, of which the following is a full, clear, and exact description, reference being hadto theaccompanyin g drawings, which form part of this specification, and in Which- Figure l represents a View in perspective of my watensprinkler, and Fig.` 2 isa transverse section through the center of the water-vessel.

My machine consists of a revolving vessel by which the wateris carried and from which it is drawn by force-pumps. The latter, beingV operated by the revolving` vessel, expel the water in a shower through numerous perfo rations in a curved pipe at the hinder end of the machine, thus sprinkling a broad strip of ground as the machine is drawn forward.

In the drawings, Ais a strong frame to which the other portions of the machine are attached, and wliichis furnished with a pole B, or with shafts to which the team is hitched. The water-vessel is most conveniently'built-like a cask for hoiding liquids-of staves suitably hooped upon two heads a a. It is encircled at each extremity by fellies C C and tires b b, which thus form the Wheels upon which the machine runs. Each head is fitted with a hollow gudgeon c, which is received in a box secured to the adjoining' side bar of the frame. Two single-acting force-pumps D D are mounted upon the hinder part of the frame. The piston-rod CZ of each pump is passed through an eye in a bail e, secured to an open end of its pump-barrel. The pump-pistons are each put in motion bya crank f, secured to a shaft supported by a forked standard g on the frame of the machine. Each piston is connected with its respective crank-pin by a connecting-rod h, which is forked to embrace the piston-rod and bail. The crank-shaft has a cog-Wheel j mounted upon it, which gears into a cog-wheel k, mounted upon the projecting extremity of the hollow gudgeon. The barrel of each force-pump is connected with the interior of the water-vessel by a suction-pipe Z, which,passing through the hollow gudgeon, is bent downward, so as to draw the water from the lower part of the vessel. The vacant space which intervenes between the suction-pipe and the hollow gudgeon is packed to prevent leakage, either by a collar of leather t', or by some other suitable means. The lower extremity of the suction-pipe is fitted with a valve fm to prevent the reiux of water from the pump-barrel when the piston is .forced inward, and each is furnished with an air-pipe n, which, passing through it into the watervessel, is bent upward to prevent t-he water from escaping through it when the vessel is full. A discharge-pipe P is fitted to the hinder end of each pump-barrel. These are also fu r nished with valves o, which close as the piston is withdrawn in its barrel to prevent the return of water into it, and their hinder eX- tremities are connected by a curved pipe E, which is pierced with numerous small holes.

The Water-vessel is furnished with a bunghole through which it can be filled. The hole is then closed, the connecting-rods are disengaged from their crank-pins, and the machine is drawn to the place where the water is to be sprinkled. The connecting-rods are then put in gear, and as the machine is drawn forward the pump-pistons, being driven by the revolving vessel, eject the water forcibly through the perforations in the curved pipe to a considerable distance on each side of the machine.

This machine from the simplicity of its parts and its efficiency is particularlyapplicable to the watering of the streets of cities, and as the watenwhich constitutes the great weight of the machine, is rolled forward in lthe revolving vesselbut comparatively little P. H. WATSON, E. S. RENWICK.
